The I
between different ICs. The SDA line is the serial data line
and the SCL the serial clock line. Both lines must be
connected to a positive supply via a pull-up resistor when
connected to the output stages of a device.
Data transfer may be initiated only when the bus is not
busy. The SAB9082 has the I
subaddresses are 00H to 18H, registers 15H to 18H are
reserved for future extensions.
